FASS Drop In Series Fuel System | Cummins ISX and X15 | DIFSHD4001
Part#:
Description
The FASS Drop In Series DIFSHD4001 brings FASS water separation, filtration and air and vapor removal to Cummins ISX and X15 engines. The Drop In Series is built to go in with far less plumbing than a frame mounted lift pump system, which matters when the truck earns its living and downtime costs money.
- Application: Cummins ISX and X15 engines
- Part number: DIFSHD4001
- Series: FASS Drop In Series, heavy duty
Air in the fuel is a bigger deal on a Class 8 engine than most people think. It shows up as lost power on grades, rough idle and injectors that wear out early. Pulling the air and water out before the fuel reaches the injection system is what FASS built its name on in the heavy truck market.
Heavy duty fitment depends on the engine, the fuel module and how the truck is plumbed. Call us with your engine and chassis before you order and we will confirm this is the right kit. If you need more fuel volume than a Drop In provides, look at the FASS Industrial Series.
